F(x)=x^3+4x−7
g(x)=6x^4−5x+2

what is f(x)−g(x)?

f(x)−g(x)=x−x
f(x)−g(x)=−6x^4+x^3+9x−9
f(x)−g(x)=6x^4−x^3−9x+9
f(x)−g(x)=6x^4+x^3−x

f(x)−g(x)=−6x^4+x^3+9x−9

Step-by-step explanation:

To find f(x) - g(x), subtract the expressions by distributing a negative into g(x) and combine like terms. Recall, like terms are terms which have the same base and exponent.

f(x) - g(x) = x^3 + 4x - 7 -(6x^4 - 5x + 2)

f(x) - g(x) = x^3 + 4x - 7 -6x^4 + 5x - 2

f(x) - g(x) = -6x^4 + x^3 + 9x - 9

im not sure

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
